Nature Communications, Published online: 12 September 2026; doi:10.1038/s41467-026-77436-w Chiral polycyclic spirocycles are privileged molecular scaffolds for drug discovery and asymmetric synthesis, yet their efficient stereoselective construction remains challenging. Here, the authors report a Pd/Sadphos-catalyzed asymmetric dearomative cascade that delivers polycyclic spiro enones with three …

Nature Communications, Published online: 12 September 2026; doi:10.1038/s41467-026-77786-5 Photoelectrochemical performance strongly depends on charge separation within space charge layer, but the precise mechanisms remain unclear. Here, the authors disentangle the effect of space charge layer width and built-in electric field on charge dynamics using in-situ time-resolved techniques.

Silicon (Si) has a high theoretical capacity of 4200 mAh/g in lithium-ion batteries anode; however, it faces three main difficulties: an unstable Solid Electrolyte Interface (SEI), particle pulverization, and volume expansion. In this work, we present a highly efficient anode material for Lithium-Ion CR2032 3V half-cell using Activated Charcoal (AC), Carbonized Sucrose Powder (CSP), and Hierarchi…

Scientific Reports, Published online: 12 September 2026; doi:10.1038/s41598-026-71361-0 Preconcentration and simultaneous determination of five anticancer drugs in biological and wastewater samples using Vortex-assisted magnetic dispersive micro-solid phase extraction coupled with HPLC

Bayer AG (Leverkusen, Germany) and Neste Oyj (Espoo, Finland), the world’s leading producer of renewable diesel and sustainable aviation fuel, have finalized a commercial agreement to jointly scale Bayer’s newgold® winter canola. The collaboration will enable Bayer to significantly expand acres of winter canola in the Southern Great Plains of the U.S., strengthening the oilseed […] The post Bayer…

Analysis revealed seed proteins from sesame and moringa, which held religious and symbolic significance.

Nature Catalysis, Published online: 11 September 2026; doi:10.1038/s41929-026-01613-9 Ni(OH)2 catalysts are commonly assumed to oxidize to NiOOH under water oxidation conditions. Now in situ surface-enhanced Raman spectroscopy and DFT calculations reveal that the catalytically active surface at relevant potentials is terminated by NiO2 as bands once assigned to superoxides instead arise from NiO2…

Stimuli-responsive nanotherapy (SRN) has emerged as a promising therapeutic strategy that employs nanosensitizers activated by external physical or chemical stimuli to generate reactive species for disease treatment. Among various nanosensitizers, metal nanoparticles (MNPs) have attracted considerable attention owing to their unique physicochemical properties, including tunable optical responses,…

Polymethoxyflavones (PMFs), citrus-derived compounds valued for their diverse biological activities, remain difficult and expensive to manufacture because production still depends largely on plant extraction. The study identifies CsOMT5, a sweet-orange gene encoding caffeic acid O-methyltransferase 5, as a key controller of PMF formation and reveals an unexpected route beginning with the abundant…

A review of rare earth element-containing materials finds that cerium, lanthanum, and other REEs can improve redox behavior, oxygen mobility, electrochemical activity, charge separation, hydrogen storage, and membrane performance across several hydrogen-production technologies. Most advances remain at laboratory scale, with wider deployment dependent on cost, resource availability, extraction imp…

Hiden Analytical has published a technical article exploring how Secondary Ion Mass Spectrometry, SIMS, can support isotope ratio analysis and depth-resolved characterization of enriched medical isotope target materials.

Nature Communications, Published online: 11 September 2026; doi:10.1038/s41467-026-77291-9 Developing durable non-noble-metal catalysts for acidic water oxidation remains challenging. Here, the authors show that neodymium doping stabilizes active Mn3+ species, enabling manganese oxide to operate for over 1000 h at 200 mA cm−2.

A team of researchers led by the University of Hawaiʻi at Mānoa Department of Chemistry has uncovered a faster way large carbon-based molecules may form in space, helping solve a long-standing mystery about how some of the building blocks of the universe grow.

Scientific Reports, Published online: 11 September 2026; doi:10.1038/s41598-026-70825-7 Efficient dark catalytic degradation of hazardous cationic dyes using a magnetic Fe 3 O 4 /rGO/CdS nanocomposite

Yes – but not consistently. Bioactive stability is influenced by heat, time, pH, oxygen, and water chemistry. According to a study... The post Do Herbal Extracts Lose Bioactives in Beverages? appeared first on Food Research Lab .
